Re: Call me superficial...
I've only nursed 2, but they were very lopsided while I was nursing. To the point where I couldn't wear certain shirts because they'd pull the neckline all out of whack and it was really ridiculously obvious.
Anyhoo, point being I weaned and within about 5 months or so they were back to (nearly) the same size. One was always slightly larger even before nursing and pregnancy so they are back to that same mild, not so noticeable lopsidedness.
Slightly flatter and don't quite 'look you in the eye' the way they used to, but not too bad overall.
